UEFI

At the time of writing, the latest kernel in [testing] (2.6.39) was unable to boot in UEFI mode on this laptop unless "noefi" was passed on the kernel line. The 3.0-rc1 kernel merged patches intended to fix this, and was able to boot, with warning messages (see kernel bug report). Version 3.6.39.1 is expected to contain the same patches.

Graphics

The integrated HD3000 GPU was found to work flawlessly, although graphical corruption was experienced in KDE SC 4.6.3 on some plasma widgets and Kwin decorations. This was found to be caused by DRI configuration related to S3TC, and was completely resolved by creating a ~/.drirc file with the following contents:

The keyboard (including number pad), power button, audio hotkeys, webcam, and microphone were found to work flawlessly without any intervention.

The "Track Stick" performs as expected. However, the multipoint touchpad is detected as a generic PS/2 mouse, and therefore does not support synaptics extensions such as scrolling or non-trivial gestures. This appears to be a kernel issue (see kernel bug report).

SD Card Reader

The kernel does not currently react when I place an SD card in the SD card reader. I'm uncertain what is causing this issue, but there appear to be reports of similar behaviour with previous Latitude models.
